Where to Buy AOD-9604 in the UK
AOD-9604 is a specific fragment of a much larger molecule, and listings frequently describe it imprecisely. This guide covers what the documentation should state and what is available.

Due Diligence
AOD-9604 Is a Fragment of hGH — Verify the Fragment, Not the Protein
AOD-9604 corresponds to the C-terminal 176-191 region of human growth hormone with an added tyrosine. Almost all confusion in this market comes from that relationship.
- STEP 01
It Is Not Growth Hormone
AOD-9604 is a short synthetic fragment, not recombinant hGH. Suppliers who blur the two are either confused or trading on it. The molecular weight difference is enormous and settles the question instantly.
- STEP 02
Also Sold as hGH Frag 176-191
The same region is sold under that name without the N-terminal tyrosine modification that defines AOD-9604. They are related but not identical, and the certificate should specify which.
- STEP 03
Disulfide Formation Must Be Correct
The fragment contains cysteine residues, so correct disulfide pairing is part of its identity. Scrambled or reduced material can pass a purity check while behaving differently.
- STEP 04
Fragment Chemistry Means Oxidation Risk
Free cysteine and methionine both oxidise on the shelf. A recent analysis date carries real weight here, unlike on an oxidation-resistant tetrapeptide.

Overview
What Is AOD-9604?
AOD-9604 is a synthetic peptide corresponding to the C-terminal fragment (amino acids 176–191) of human growth hormone, studied in metabolic research models. Because it is a defined fragment rather than a full-length molecule, the Certificate of Analysis should state the fragment range explicitly. It is supplied as lyophilised powder in a sealed vial.
Classification
Synthetic growth hormone fragment
Format supplied
vial
Relationship to hGH
Synthetic analogue of the hGH(176-191) C-terminal fragment with an added tyrosine
Structural note
Contains cysteine residues; correct disulfide pairing is part of the specification
Purity specification
HPLC assay, 99% minimum, chromatogram provided on request and with the order
Research use only
Not a medicine. Not for human or veterinary consumption.
Available Options
AOD-9604 Options Available From Arma Peptides
AOD-9604 is supplied as a single lyophilised vial size. Because oxidation is the limiting factor rather than time in the freezer, matching purchase to use is worthwhile.

Handling & Delivery
AOD-9604 Handling: Disulfides and Oxidation
The handling rules for AOD-9604 all trace back to the cysteines in the sequence.
Minimise Air Exposure
Cap the vial immediately and keep bench time short. Oxidation of cysteine and methionine residues is the main degradation route and it is entirely a function of exposure.
Do Not Add Reducing Agents
Reconstitute in plain bacteriostatic water. Any reducing agent will break the disulfide and the resulting material is no longer the compound you bought.
Cold and Dark, Aliquoted
Sealed powder at −20 °C for long holding; reconstituted solution refrigerated, protected from light and divided into single-use aliquots.
Dispatch and Cover
Same working day dispatch before the cut-off, tracked and plain-packaged, with 48-hour photographic damage cover for replacement or full refund including return postage.
FAQ
AOD-9604 in the UK: Questions Researchers Ask Before Ordering
+Is AOD-9604 legal to buy in the UK?
For laboratory research, yes. It is not a licensed medicine, must not be marketed as one, and must not be used for human or veterinary consumption.
+Is AOD-9604 growth hormone?
No. It is a short synthetic fragment based on the C-terminal 176-191 region of human growth hormone, with an added N-terminal tyrosine. Recombinant hGH is a full 191-residue protein and a completely different product.
+How does AOD-9604 differ from hGH Frag 176-191?
AOD-9604 carries an N-terminal tyrosine modification that the plain fragment does not. They are close relatives, so the certificate needs to state which sequence was synthesised and analysed.
+What does the 176-191 designation mean?
It identifies which amino acids of the parent growth hormone sequence the fragment corresponds to — residues 176 through 191. A COA that does not state the fragment range is not fully identifying what is in the vial.
+Is AOD-9604 the same as growth hormone?
No. It is a short synthetic fragment of the C-terminal region, not the full-length 191-amino-acid molecule, and it is studied for a different research profile.
+Why does disulfide pairing matter?
Because the cysteine residues in the fragment must pair correctly for the molecule to have the structure stated. Scrambled or reduced material can still return a respectable HPLC purity figure while being structurally wrong.
+What storage does it need?
Sealed at −20 °C for long-term holding, 2–8 °C short term, with minimal air exposure. Reconstitute in plain bacteriostatic water and never in a diluent containing reducing agents.
+Can I return an unopened vial?
Yes, within 14 days of receipt if unopened and in original sealed packaging. Unsealed vials are excluded for health-protection reasons and your statutory rights are unaffected.
